本研究檢視了中文版健康焦慮問卷(Chinese version of Health Anxiety Questionnaire,C-HAQ)的心理計量特徵,並探索其與DSM-IV身體型疾患、DSM-5身體症狀及相關障礙症之關係。結果顯示,C-HAQ之內部一致性為0.943,再测信度為0.958,均在良好範疇。探索性因素分析顯示其有對健康與疾病的過度擔憂、症狀對生活干擾程度、尋求再保證之行為三個因素。與其他憂鬱,焦慮,身體症狀量表之相關性為中等。CHAQ應用於DSM-5身體症狀及相關障礙症之評估,具有比評估DSM-IV身體型疾患更佳之表現;不論對應於何種系統,17/18都是判斷是否具有診斷的適宜切點。
In this study, we examined the psychometric properties of the Chinese version of Health Anxiety Questionnaire (C-HAQ), and explored its association with somatoform disorders in DSM-IV, and somatic symptom and related disorders in DSM-5. We found good internal consistency (0.943) and test-retest reliability (0.958) of C-HAQ. Exploratory factor analysis reveals three factors: excessive worry to health and illness, extent to which symptoms interfere with a person's life, and reassurance-seeking behavior. It has moderate correlation with depression, anxiety and somatic constructs. According to the result of ROC curve analysis, C-HAQ has better performance in evaluating DSM-5 somatic symptom and related disorders than in evaluating DSM-IV somatoform disorders. No matter applying which diagnostic system, 17/18 is a proper cutoff for making the diagnosis.
